SHLL (SHift Logical Left)
Operation
Rd (left logical shift)
Assembly-Language Format
SHLL.W Rd
Operand Size
Word
Description
This instruction shifts the bits in a 16-bit register Rd (destination operand) one bit to the left. The
most significant bit (bit 15) shifts into the carry flag. The least significant bit (bit 0) is cleared to 0.
Available Registers
Rd: R0 to R7, E0 to E7
Operand Format and Number of States Required for Execution
Notes
